Abstract: 1,262,148. Soldering. G. LAUBMEYER, and M. SMITS,- [trading as ZEVA-ELEKTRIZITATS-GESELLSCHAFT SMITS UND LAUBMEYER K.G.] 12 March, 1969 [13 March, 1968], No. 13000/69. Heading B3R.  Apparatus for soldering two parts together, of which at least one is tinned, comprises means for pressing the parts together, means for applying heat to the parts and means responsive to relative movement of the parts together upon softening of the tinning therebetween and serving to switch off the electric current supplied to the heating means when the parts have moved together through a predetermined distance. An apparatus for soldering a component 8 to a printed circuit 5, both of which are tinned, comprises a base 2 carrying a heater 4 and a column 3 carrying adjustably above the base a table 6 and at a higher level a support 12 for a clock type gauge 1. In operation the printed circuit 5 is arranged on a glass plate 7 mounted on the table 6 and the component 8 is pressed resiliently on to the circuit 5 by the plunger 11 of the gauge and the gauge reading is noted. The heater 4 e.g. a lamp then heats the joint and as the tin layers soften the component sinks towards the circuit and the gauge registers an increased displacement of the plunger 11. Means responsive to the movement of the hand of the gauge, e.g. a selenium cell operating a relay, cuts off current supply to the heater. The hand may alternatively move a metal plate of a condenser or an inductive means can be used to switch off the heater. A vibrator 14 is provided to ensure that the gauge does riot stick during the process. In a modification the heat applying means is a resilient heating tape with resilient curved parts in the limbs of the U, the tape being supplied at its ends with low voltage current and the plunger of a clock like gauge being engaged within the U-shape tape. When the work sinks during heating the current to the tape is cut off. The tape may be of beryllium-nickel-chromium alloy which is not readily tinned; In another modification a U-shape tape, not in itself resilient, is pressed by a spring or weight loaded plunger whose upper surface is engaged by the plunger of the gauge.

Abstract: 436,309. Automatic regulation. POLLARD & CO., Ltd., E., 159, St. John Street, and HAMMOND, E. N., 26, Fordhook Avenue, Ealing Common, both in London. May 1, 1934, No. 13119. [Class 38 (iii)] In a control system for a lift &c. motor which runs at various speeds means are provided for obtaining a fixed crawl speed comprising a rotating member 4, Fig. 1, driven at a constant speed and another member 11 driven in the same direction at a speed corresponding to the speed of the motor to be controlled, the members actuating contacts in a circuit which effects control of the motor. Two contacts 6, 7 are mounted on the member 4, between which a third contact 10 loosely mounted on the shaft is situated. This contact is in friction engagement with the member 11. Fig. 3 shows the circuit diagram, assuming that the controls are set to crawl speed, the contactor coil 25 is open circuited causing the eddy current brake 26 to be applied. According to the direction of movement of the lift either switch 20<a> or 21<a> will be closed. If the motor is too slow contact 10 moves out of engagement with contact 6 and contactor coil 30 is de-energized to short circuit a resistance in the rotor circuit of the motor. If the motor speed still remains low the contact 10 engages the contact 7 to energize contactor coil 32 and remove further resistance from the motor circuit. The reverse action takes place to lower speed. The eddy current brake 26 and electromechanical brake 33 are de-energized when the lift is stationary by contactors 20b and 21b. The contacts 20<a>, 21<a> serve as a reversing switch to change over the connections of the contacts 6, 7 when the action of the lift reverses. A reversing switch is also provided to reverse the rotation of the motor driving the disc 4. Specification 424,994 is referred to.

Abstract: 757,829. Pitot-tubes. KOLLSMAN INSTRUMENT CORPORATION. May 7, 1954, No. 13394/54. Class 69 (1). A pitot-tube device for measuring wind speed and direction and having no exposed moving parts comprises a substantially flat disc-like shell with conduits enclosed therein and terminating in pressure openings evenly spaced round the periphery of the shell, and a mounting member connected to one of the flat surfaces of the shell and through which the conduits extend. The shell may include an electric heating coil; as shown, the shell 1 is formed as a body 3 mounted on a shaft 4 with threaded mounting portion 4a and a top cover plate 2. The body 3 has four pressure apertures 4 disposed in quadrature and connected in pairs so as to measure, say, the North-South and East- West components of wind velocity. These components are converted into proportional A.C. voltages and applied to perpendicular windings of a rotary transformer; perpendicular secondary windings are positioned so that the voltage in one is a measure of the magnitude of the wind speed by using the voltage induced in the other to control a motor so as to bring this voltage to zero, the position of the rotor then indicating wind direction.

Title: Electronic data storage devices
IPC: G06F17/30
Filed: 1975-04-02
Abstract: 1508353 Associative storage system SIEMENS AG 2 April 1975 [11 April 1974] 13420/75 Heading G4A An associative storage system generally similar to that described in Specification 1,475,785 is arranged to store data words of a length an integral multiple (1.2.3...) of that which can be stored in any one storage bank, there being a multiplexer arranged to feed to each of an appropriate number of storage banks, determined by decoding a length code associated with each data word, the address selected for use in the storage bank storing the first part of the word, whereby for a long word several storage banks each store a part of the word at the same address. As stated above the arrangement described is similar to that of Specification 1,475,785. An address decoder ADW decodes from part VS of the input word a 16 bit address and each storage bank B0-B7 receives a different 8 bit address combination from the 16 bits which, in combination with the contents of extension counter EZ, addresses the storage bank. Muliplexer MPX, in response to code FLK indicative of the length of the input word, passes the address used in that storage bank which is to store (or which could store if a search is being performed) the first part of the input word to that storage bank and to the appropriate number of following banks. The arrangement is such that storage bank s2p stores the first part of a word of length n times that which can be stored in one bank where n#2p<2n with n, p, and s being integers. When storing of a word, particularly a long word, is not possible a relocation procedure or the extension counter is used to enable the word to be stored, see Specification 1,475,785. The priority arrangements for determining where to store words when more than one location is free, differ from Specification 1,475,785. The locations in each bank are divided into groups which are ordered in priority and a part of the address established for each bank is fed to a priority device which selects the highest priority selected group but only if the addressed location in that group is free. If two storage banks have the same address group a further priority device selects one of the storage banks on a priority basis. This arrangement tends to concentrate data towards low (or high) valued addresses in the storage banks thereby leaving higher (or lower) valued addresses free in all storage banks to receive long data words.

Abstract: 815,116. Photo-electric instrument monitoring. BECKETT & PARKER Ltd. April 23, 1957 [May 3, 1956], No. 13635/56. Class 40 (3). A shutter attached at an intermediate position to and forward of the plane of an instrument needle interrupts light incident upon a light-sensitive cell, the light source and cell being on a common mounting rotatable around the axis of the needle. A strip of foil 16, Fig. 2, fastened to an ammeter needle 2 interrupts the light of a lamp 9 falling on a transistor 5. Lamp 9 and transistor 5 are mounted on a pivot 7 and clamped by a nut 13, their position being indicated by a finger 15. The transistor 5 is connected to an amplifier and a relay or trigger circuit to operate a cut-out device when the current in the ammeter exceeds a certain value. The photo-cell 5, Fig. 5, and illuminating lamp 9 may instead be coupled to a shaft 21 operated by reduction gearing 22 driven by motor 23, which. in turn is controlled by the output of the photocell, a signal from which stops the motor 23 so long as the position of coincidence is maintained. When it is disturbed the cell and lamp are again allowed to scan across the path of the needle 2. A belt and pulley power take-off 25 operates the arm of the potentiometer 26, the voltage across which is fed to voltmeters R which serve as repeaters.

Filed: 1975-04-03
Abstract: 1470148 Marine seismic surveying WHITEHALL CORP 3 April 1975 [9 April 1974] 13642/75 Heading G1G A streamer section 14, for a marine seismic streamer made up of a plurality of sections serially connected together, comprises a jacket 16, a pair of cylindrical pistons 23, a pair of hydrophone mounting members 30 fixed to adjacent mounting faces of said pistons, a pair of hydrophone units 18 respectively supported in said mounting members 30, and means for adding the output signals from the hydrophones. Unwanted noise signals transmitted along streamer components, such as the strain cables 17 and the liquid streamer filling, are eliminated by positioning the pistons of a pair about 4 ins. apart so that signals reaching said pistons are equal in phase, amplitude and frequency and the corresponding sound fields generated in the liquid surrounding the hydrophones are identical in magnitude but opposite in sign. The output signals from the hydrophones therefore tend to be cancelled when they are summed. Mounting member 30, preferably made of polycarbonate, is cylindrical with a closed end 38, the opposite end having four holes (35), Fig. 4 (not shown), and two small holes for the signal wires, said member 30 having mounting legs 36. The hydrophone 18 is positioned by members 31, and comprises a Piezo-electric ring 19 and concave diaphragms 20. Signal wires from the pairs of hydrophones are carried in a bundle 28 to an impedance matching transformer and processing equipment in the towing vessel. The pistons are held stationary relative to the strain cables 17 and jacket 16 respectively by filling bores 25 with solder or similar material and by making the piston 23 a tight fit in the jacket or clamping the two together with a hose clamp 26. Fluid-tight seals are made around the strain cables and bundle of signal wires by filling bores 24A and 27A with a sealer such as epoxy adhesive. Successive pairs of hydrophone units may be placed about 6 feet apart in the streamer.
